摘　　要：本文根据京西山地油松(Pinus tabulaeformis)三块不同海拔试验林7年生时的材料,研究了油松不同生态型在不同海拔高度试验地的生长表现。结果表明,油松不同生态型之间的生长表现存在显著差异,而且生态型×不同海拔试验地交互作用显著。在海拔800m以下,东部型生长和稳定性均比其他生态型好。在800—1200m地带,表现较好的是东部型,其次是中部型和中西型。在1200m以上地带,东部型和东北型生长表现较好。根据试验结果,提出京西山地如采用东部型的种子,可不考虑造林地的海拔高度,也不必考虑种子来源上的海拔差异。此外,在造林种子短缺时,800—1200m地带还可采用中部型和中西型的种子,1200m以上还可采用东北型的种子。The paper deals with the growth performances of different ecotypes of Pinus tabulaeformis in three different elevation sites in Beijing mountain area. The 7-year-old results show that there are significant differences in growth performances among the ecotypes and the interaction between ecotype and site is also significant. In the sites below the elevation of 800 metres, the eastern ecotype is best because of its fast-growth and stable performances. The eastern ecotype, the central ecotype and the central-western ecotype are suitable for the sites with the elevation of 800-1200 metres. In the sites above the elevation of 1200 metres, the eastern ecotype and the north-eastern ecotype grow fast and have better performances. According to the results, it was put forward that the elevation differences between both the sites and the seed origins may not be considered if the seeds from the eastern ecotype are adopted in Beijing mountain area. Additionally, the seeds from the central ecotype and the central-western ecotype could be adopted in the sites with the elevation of 800-1200 metres as well as the seeds from the north-eastern ecotype in the sites above the elevation of 1200 metres on the condition that the seeds are in short supply.
